Answer:
Y x 3 - 3 = Y + 57
30 would be your answer
add 3 to both sides so it becomes Y x 3 = Y + 60 and 60/2=30
30 x 3 = 90-3=87
30 + 57 = 87
Hope this helps (I am twelve and I know how to do this)
Step-by-step explanation:
Y=2×2
y=4
4=-3x-1
now add 3x on both sides
3x+4= -1
now substract 4 on both sides
3x = -5
divide 3 on both side
x=-5/3
y= 4
x= -5/3
Answer:
$694.06
Step-by-step explanation:
OG price= 1,029
discount=.05
sales tax =.065
1/3(og price)=1/3(1029)=343
one third of $1,029 is 343, hence we take off $343 from the orginial price
1029-343= $686--> sales price
.05*salesprice= .05*686=34.3
subtract 5% discount: 686-34.3= $651.71
=find 6.5% tax: .065*651.71= $42.36
add 6.5% tax: 651.81+42.36=694.06
Chord AB = ?
Chord AB = AC + CB
Chord HI = HC + CI
HC = 7
CI = 28
Chord HI = 7 + 28 = 35
Chord AB = Chord HI
CB is 4 times the Length of AC. Let AC be X.
x + 4x = 35
5x = 35
x = 35/5
x = 7
AC = x = 7
CB = 4x = 4(7) = 28
Answer:
6
Step-by-step explanation:
y=mx+b
93.40=8.40x+43
the 93 is the amount we want to get to, 8.40 represents the value of each sign and the 43 is the original cost
